Hydrostatic Drive for Three-Wheel Vehicle

The vehicle shown in Fig. 6.17 has three wheel motors supplied by the same pump. In the design of such a vehicle, care must be taken to size the motors and final drives such that the tangential velocity of the front and rear wheels is approximately equal. The flow does divide in such a manner that the pressure drop across the front and rear motors is approximately equal. There are considerations in the design which are beyond the scope of this discussion.
